Professional Consultations
There are many times when you need an answer to a technical query relating to the products that you or your company trade. While you can ask a mate or "look it up on the internet" - when you need accurate information, you can seek professional assistance from David J Heffer and Associates. Consultations are available on a fee-for-service basis.
Consumers who return products because they are unsatisfactory are a wonderful source of product information. Many clients have these products tested to check the validity of the complaint. Valid complaints can be used to prevent similar problems in the future. The furniture industry uses this service extensively to determine if claims are due to abuse, a fabric fault, incorrect upholstering, unsatisfactory furniture manufacturing practices or some other cause.
Detergent and Pre-Wash Stain RemoverEvaluation
Manufacturers of detergents and pre-wash stain removers use our service to compare their product with others in the same market segment. Similar evaluations can be performed on fabric softeners.
Common fabric types are soiled with a variety of soil types and subjected to carefully controlled wash cycles. The levels of soiling are measured before and after washing using a spectrometer which provides an objective measure of soil removal. Statistical analysis allows us to identify particular types of soil or fabric types that are most (or least) effectively cleaned by the product. The products included in the trial can be ranked in order of general effectiveness or for particular soils.
David J Heffer is a Chartered Textile Technologist who has provided expert evidence in many legal matters.
Leather Care Product Evaluation
Leather cleaners, leather conditioners and leather protectors can be evaluated for their effectiveness on the approriate leather type - top coated, nubuck, aniline or suede. These evaluation also ensure that the appearance and performance of the leather are not negatively affected by the product.
We bring a fresh view to the problems that arise in many businesses that deal with textiles. By combining our expertise with your specialist knowledge and utilizing our laboratory facilities, we can help you get back to your core business.
We can prepare a specification for your fibre, yarn, fabric or garment, or other type of product. The specification reflects your quality aspirations - it makes sure that your product has the performance and cost that you intend.
Specifications make sure that you maintain a consistent level of quality - one that you and your customers can depend on. It is not about creating a product that has the highest performance and the greatest price - just the cost and performance that suits your market.
Specifications help to select fabrics from an alternative supplier. They help to avoid an erosion of quality over time or when changing to a new supplier. This is the trap set by the assurance that "...This one is just as good as your current fabric".
The cost of preparing a fabric specification is rapidly repaid by the savings of buying the right fabric (not the most expensive), by rejecting unsuitable fabric without the cost of sampling, by rejecting unsatisfactory batches without the cost of losing customers due to sub-standard goods.
